Subject [jira] Commented: (DERBY-3959) Reference Manual needs information on generated columns
Date Tue, 16 Dec 2008 15:24:46 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3959?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12657016#action_12657016
] 

Kim Haase commented on DERBY-3959:
----------------------------------

Another question: for the syntax

  GENERATED ALWAYS AS ( values-expression )

how should I define "values-expression"? I can't find it elsewhere in the Reference Manual.
Is it any of the expressions described in "SQL expressions" (http://db.apache.org/derby/docs/dev/ref/rrefsqlj19433.html)
or are there limits?
